φ2700×3600球磨机进料与中空轴之间的防砂问题,原设计是用五合板和灌沥青充填的办法。由于五合板和灌沥青受施工条件的限制,充填达不到理想的要求。球磨运转起来,筒体内的砂浆就进入到进料斗与中空轴之间。时间一久,球磨中空轴内孔就慢慢被磨大,我厂甚至发生把中空轴磨断了的现象。为此,我们对进料斗进行了改进(附图)。在进料斗靠筒体的一端加工一段带锥度的台阶,另外加工一个与进料斗锥度相同的挡圈,挡圈外圆焊在球磨机进料端盖上,进料斗与挡圈之间用橡胶或石棉绳作密封充填,这样矿浆就磨
φ2700 × 3600 sand mill between the feed and the hollow shaft sand control problems, the original design is filled with pentagonal and irrigation methods. As the plywood and irrigation asphalt by the construction conditions, filling less than the desired requirements. Ball mill operation, the mortar inside the cylinder into the hopper and the hollow shaft between. Over time, ball mill hollow shaft hole is slowly grinded, and even the occurrence of the hollow shaft abrasion phenomenon. For this reason, we improved the feed hopper (with photos). One end of the feeding hopper on the cylinder body is machined with a taper step, and the other is processed into a ring with the same taper as the feeding hopper. The circling ring is externally welded on the feeding end cap of the ball mill and between the feeding hopper and the circlip Seal with rubber or asbestos rope filling, so the pulp on the mill
